The brave woman, who lived in Greece for over 10 years, is going through a painful Efudix treatment after she was diagnosed with Actinic Keratosis in December.

On the Facebook page, titled Mag’s Murphys Journey, the Dublin mum is documenting her journey on a daily basis to highlight the dangers of the sun and using sunbeds.

Margaret admitted that she is paying the price for not using sun protection throughout her life.

She said: “I’ve spent over a decade living in Crete tanning myself to ‘look good’ thinking hey I’m brown I don’t need high sun factor, I’ve spent summers doing sunbeds just for a tan in the s****y Irish weather and a childhood running the streets all day with not a thought for sun factor.

“Unfortunately all this lovely tanning has a price to pay cause now I have pre-cancerous cells on my face and have started treatment to remove them.

“I’ve to use a cream that’s going to burn them out,apparently it’s quite painful and gruesome as the weeks go on but on the good side it should get rid of the cells and treatment and is only for a month.”

The Irish mum-of-one said she is hoping that her daily posts will help someone learn from her mistakes.

Margaret said: “I’m sharing this to try and raise awareness to sun damage and using high factor sun lotion.

“I heard all the warnings years ago and closed my eyes and ears to it all, maybe someone will open their eyes to this if it’s closer to home.”

The former sun-worshipper said she noticed she had marks on her forehead for almost nine years but one doctor told her it was psoriasis so as a way of healing she had exposed them even more to the sun.

Margaret said: “I had visible marks on my forehead for eight or nine years but because you could cover them with my hair they didn’t bother me, one doctor actually told me it was psoriasis so at one stage I was letting the sun at them because I heard it was good for psoriasis.”

She added: “They were constant little crusty spots that would never go away no matter what I put on them.”

From day 3 of the treatment, Margaret posted daily photos of her face which was becoming redder each day.

On day nine of the painful treatment Margaret said her face felt like someone had ‘put a cigarette out on me’.
